Joint Analysis of Shannon and Tsallis Entropy and GRACE-FO driven Equivalent Water Height Anomalies for Pre- and Post-Rupture Monitoring: An Example of the 2023 Mw = 7.8 KahramanmaraŠEarthquake, Türkiye
Muhammed Hossein Mousavi, Hamzeh Mohammadigheymasi, Amirreza Moradi
In order to understand the variations in fault systems throughout the seismogenic cycle, mechanical states and the complexities of seismic interactions must be considered. In this…
Cross-Sectional and Spatio-Temporal Analysis of Seismicity Parameters in the Zagros Orogenic Belt: Insights into Crustal Stress Distribution and Seismic Hazard
Muhammed Hossein Mousavi, Marjan Tourani, Amir Talebi +2
The Zagros Orogenic Belt, formed by the Arabian-Eurasia collision, is a highly active collision zone hosting a large portion of Iran's seismicity. In this study, the IRSC catalog (…
Crustal Structure Imaging of Ghana from Single-Station Ambient Noise Autocorrelations and Earthquake Arrival Time Inversion
Hamzeh Mohammadigheymasi, Courage K. Letsa, Nasrin Tavakolizadeh +5
The crustal architecture of southern Ghana remains inadequately resolved despite its tectonic significance and resource potential. Existing geological and geophysical studies provi…
Integrating b-Value and Background Seismicity Rate for Spatial Earthquake Forecasting in the Alborz Region, Northern Iran
Muhammed Hossein Mousavi, Hamzeh Mohammadigheymasi, Parva Sadeghi Alavijeh +1
In this study, we evaluate the spatial forecasting skill of the -value and background seismicity rate across the Alborz region using a homogenized catalog of 23,961 earthqu…
Seismic Depth Imaging of the 2024 Noto Earthquake (M7.6) Rupture Area
Hamzeh Mohammadigheymasi, Jin-Oh Park
On January 1, 2024, a moment magnitude (Mw) 7.6 earthquake struck the Noto Peninsula, Japan, causing intense ground shaking and triggering a tsunami along the Japan Sea coast. Prel…
Earthquake body wave extraction using sparsity-promoting polarization filtering in the time-frequency domain
Hamzeh Mohammadigheymasi, Bahare Imanibadrbani, Ali Gholami +1
Seismic waves generated by earthquakes consist of multiple phases that carry critical information about Earth's internal structure as they propagate through heterogeneous media. Th…
